GoodWe Lynx Home F 13.10 kWh (PCU base + 4 x LX F3.3-H)
Description
Storage expansion without touching existing solar strings.
GoodWe GW8K-BT is an 8 kW three-phase AC-coupled storage inverter delivering 8,800 VA maximum apparent power and 25 A battery throughput, engineered to add high-capacity battery storage to existing 8–12 kWp solar systems without touching rooftop DC wiring.
Drop-In Three-Phase AC Storage Retrofit
Upgrades existing three-phase solar systems to high-voltage battery storage without modifying rooftop arrays.
8,800 VA Maximum Apparent Throughput
Delivers robust continuous power to run domestic appliances, heat pumps, and backup sub-panels from storage.
Direct High-Voltage Battery Interface (180–600 V)
Pairs natively with GoodWe Lynx Home F and Lynx D battery stacks at up to 25 A charge/discharge speed.
Sub-10 ms Seamless Emergency Power
Automatically keeps critical three-phase home circuits powered during unexpected utility blackouts.
More product details
Upgrading an operating 8–12 kWp solar plant by replacing inverters requires costly DC rewiring and scaffolding. The GW8K-BT connects straight to the home's 400 V AC distribution board, capturing surplus solar from the AC grid.
- Connects directly to the main domestic AC panel beside existing string inverters of any manufacturer.
- Measures household grid import/export in real time via the GoodWe GM3000 smart meter.
- Automatically schedules charging during solar overproduction peaks and off-peak utility tariff windows.

Direct high-voltage battery coupling with instant emergency power.
Direct high-voltage battery pairing (180–600 V) eliminates heavy step-up conversion losses, while internal high-speed switchgear provides sub-10 ms emergency power. Pairs directly with GoodWe Lynx Home F (6.55–16.38 kWh) and Lynx D high-voltage batteries at up to 25 A. Sub-10 ms automatic UPS transfer keeps home computers, routers, and heating electronics live during outages. IP66 cast-aluminum casing allows clean indoor utility mounting or outdoor sheltered installation (-35 to +60 °C).
Runs peak conversion at 97.6 percent
Three-phase power electronics hold 97.6 percent peak efficiency. Lower conversion loss keeps more of each charge cycle in the pack.
Sits in a 415 x 516 x 180 mm IP66 shell
The same BT wall footprint takes the 8 kW rating. Dust and weather sealing stay at IP66 for indoor or outdoor mounts.
Talks to meters and portals on RS485
RS485 plus WiFi or LAN carry commissioning and live telemetry. One chassis covers local bus and network links.
Technical data
High-throughput storage retrofit engineered for electrified residences with heat pumps and EV chargers.
8 kW / 8.8 kVA AC-coupled three-phase storage inverter for high-demand homes.
Sized for larger residential solar installations, the GW8K-BT delivers 8,000 W continuous AC power (8,800 VA max) to charge and discharge high-voltage battery storage. It connects straight to the home's 400 V sub-panel, enabling high-rate self-consumption and whole-home backup without touching existing string inverters or voiding existing solar equipment warranties.

Project scenario
Upgrading Existing 8–12 kWp Three-Phase Solar Systems to Battery Storage
Homes with an existing 8–12 kWp solar installation seeking to add 9.83–16.38 kWh of storage to cover heavy evening heat pump and appliance loads.
8 kW continuous AC throughput provides the power needed to discharge storage rapidly for evening cooking, heating, and lighting without drawing from the grid.

GoodWe BT Series 5-10kW AC-Coupled Retrofit Inverter Datasheet GoodWe ET/ET+/BT Series User ManualProduct questions
Can the GW8K-BT charge the battery from an existing non-GoodWe solar inverter?
Yes. Universal AC compatibility with any existing solar inverter brand. Because the GW8K-BT connects to the home's standard 400 V AC distribution board, it does not care what brand of solar inverter is installed on the roof (SMA, Fronius, SolarEdge, Huawei, etc.). The GoodWe GM3000 smart meter measures net power exchange at the utility meter and signals the GW8K-BT to absorb excess AC solar generation into the battery bank.
What is the maximum continuous AC export current on this model?
13.3 A per phase; 16 A or 20 A 3-pole circuit breaker. The GW8K-BT delivers a nominal continuous output current of 12.1 A per phase (max output current 13.3 A @ 400 V). A 3-pole 16 A or 20 A circuit breaker (MCB) on the main distribution panel is standard for European installations.
